We present the results of studying the behavior of temperature and of the atomic oxygen concentration in the mesopause region during the 2013 January major Sudden Stratospheric Warming (SSW). The data on the hydroxyl molecule OH(6-2), 834.0 nm emissi

Data about the variations of mesopause temperature (∼87 km) obtained from ground-based spectrographic measurements of the OH emission (834.0 nm, band (6-2)) at Irkutsk and Zvenigorod observatories were compared with satellite data on vertical tempe

Interaction of atmospheric non-stationary stream with obstacles on the Earth's terrestrial surface causes disturbances which are a source of various wave processes. A study of such processes and their influence on the upper atmosphere temperature reg

Using data on temperature of the atmosphere at heights of 30–100 km measured by rocket and spectrophotometric methods in middle latitudes we study the altitude distributions of the temperature response on solar activity. The large seasonal variatio

An empirical model of the mid-latitude (40°N–55°N, altitudes 25–110 km) monthly averaged vertical structure of temperature and number density is presented. It is based on the Soviet and Russian rocket, emission and radioionospheric temperature

Temperature distributions with height (70–130 km) are constructed from EISCAT radar measurements at high latitudes and spectrophotometric measurements of hydroxyl emission (87 km), sodium (92 km) and of atomic oxygen emission of 557.7 nm (97–102

The vertical influx of gravity wave energy into the mesosphere, generated by gusts of wind over a mountain chain has been calculated. There is a satisfactory agreement between the spatial distributions of the calculated energy flux and the measured t

On the basis of spectral observations of the hydroxyl emission (band (6-2), 834 nm) in the Eastern Siberia, at Tory (52N, 103E), and in the European Russia, at Zvenigorod (55.7N, 36.8E), during 2008-2011 the statistically significant seasonal variati

Long term temperature measurements of the mesopause and lower thermosphere give a possibility to obtain altitude profiles of the mean annual temperature and to reveal a regular occurrence of the temperature maximum for heights of 85–95 km, the ampl
